Includes Compu Music Accompaniment & Rhthm & Auto Accompaniment sections.via Wikipedia: "1983 - Korg SAS-20: The SAS-20 was Korg’s first arranger keyboard. A built-in computer analyzed the melody played on the keyboard, and generated a complex accompaniment. This was the world’s first auto-accompaniment function of this kind added to a keyboard. Also, a more traditional chord recognition system was included."
Curious what sound engine it had on board. 1983 would put it in time with the Poly-800. You can find an ad for it here.
